The building we bought to house our shop used to be a theater in years past. It works out great for us in that we have 4200 sqft of open area. Where the floor used to slope for the seating area we leveled out with a wood floor. After spending many years of working on concrete floors, I can't begin to say how nice it is to work on wood floors. Kinda like floating on air, my feet no longer hurt after a long day.
